An antispam client, the QOE Loader is the background process of CA Antispam that monitors your mail service. As long as it is running, when you open Outlook Express to download your new email, it parses your messages and checks for known spam or malicious emails. If they are detected, they are not delivered to your inbox. Founded in 2003 in California, Qurb, Inc. was purchased by CA in 2009.
If you want a detailed security rating about your QOELoader.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk.
If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection!
